It was probably the most spectacular music launch for a Bollywood movie in recent times, but the excitement seems to have got to actor-producer Aamir Khan who is now down with fever.

"Just got back home after a long day. Down with fever. I guess the excitement of the 'Peepli Live' music launch last evening (Tuesday) got to me. Pill time, " Aamir posted on his Twitter page Tuesday night.

Aamir broke into an impromptu gig with the Indian Ocean band at the music launch in Mumbai. He also played the drums with the well-known band that has composed the music for the Anusha Rizvi-directorial debut.
